During its caterpillar stage, the leopard magpie moth feeds on a plant called the Natal grass cycad and by so doing laces its body with macrozamin, a toxin that makes the moth highly unpalatable to would-be predators. Since the Natal grass cycad is now endangered and facing extinction, the leopard magpie moth is also in danger of extinction.
Which one of the following is an assumption required by the argument?
(A) Feeding on the Natal grass cycad is the only means by which the leopard magpie moth can make itself highly unpalatable to predators.
(B) The leopard magpie moth does not have the speed or the agility to escape from any of its potential predators.
(C) Potential predators of the leopard magpie moth cannot determine from appearance alone whether a moth’s body is laced with macrozamin.
(D) Leopard magpie moths are not able to locate Natal grass cycads unless those plants are abundant.
(E) None of the potential predators of the leopard magpie moth have developed a tolerance to macrozamin.

One can always trust LSAT questions to contain at least 1 convincing trap - but I don't think they got me!
The answer is A.
(A) Feeding on the Natal grass cycad is the only means by which the leopard magpie moth can make itself highly unpalatable to predators.
Perfect choice. The argument claims: Unavailability of Natal grass -> No longer unpalatable to predators -> Extinction from predation. This answer choice attacks the first logical step - if the grass ISN'T the only thing that makes the moth unpalatable, then the argument falls apart - there may be other ways that the moth can make itself a yucky snack - no extinction! I was ready to pick this answer and move on without reading the rest, but that's not how one answers CR!
(B) The leopard magpie moth does not have the speed or the agility to escape from any of its potential predators.
Incorrect. Let's say the moth DOES have the speed to get away from some (i.e. not none) of it's potential predators - so what? It's probably now looking all the more palatable to the predators from which it can't use it's speed to escape. Those predators now view the moths as extra tasty due to no cycad. B isn't a required assumption.
(C) Potential predators of the leopard magpie moth cannot determine from appearance alone whether a moth’s body is laced with macrozamin.
Incorrect. If predators COULD determine from a distance the lack of macrozamin, that may spell even further trouble for the moths. Predators would be smacking into eachother from a distance to eat them! In any case, C is not a required assumption.
(D) Leopard magpie moths are not able to locate Natal grass cycads unless those plants are abundant.
Tempting! But still incorrect. The argument doesn't refer to a world where there is still a low supply of Natal grass; it refers to a world in which the plant is extinct. The argument is - if this plant goes extinct, the moths go extinct too. ALSO, extinction does not presuppose a gradual reduction, from abundant to scarce, in the number of plants. The plant may be endangered because of a looming temperature increase - thus, they may go from 100 to 0 in short order! This further weakens this answer choice.
(E) None of the potential predators of the leopard magpie moth have developed a tolerance to macrozamin.
Incorrect. Extreme language - always a good sign when you want to eliminate an answer choice. 1% of the predators may have adapted to the presence of macrozamin, but what about the other 99% against which macrozamin is a legitimate deterrent. Not a required assumption by any means.
I hope this helps. I'm pretty confident in my reasoning here. Bring on the OA!
